RUDOLPH SCHNEIDER, JR., 0F MONROE, WISCONSIN.

SLIDING-DOOR HANGER.

To all whom t may concern Be it known that I, RUDOLPH SCHNEIDER, J r., citizen of the United States7 residing at Monroe, in the county of Green and State of Wisconsin, have invented certain new and useful Improvements in Sliding-Door I-Iangers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This l invention relates to door hangers, and more especially to the roller carriages employed therein, and the object of the same is to produce a. hanger whose rollers are adjustably or reversibly mounted in its carriages so that the latter may be applied with either side plate out. To this end the carriage is in two plates or parts connected by the horizontal and vertical pins which form the bearings for the said rollers and held in connected positionby the bolts which attach the parts to the door.

Other details of the carriage are hereinafter more fully described and claimed, and are shown in the drawings wherein- Figure l is a side elevation of a portion of a freight ear with this improved door and hanger applied; Fig. 2 .is an enlarged view of the hanger alone,` as seen from the inside; Figs. 3 and 4L are sections through the hanger part of the framework of the car, and the door, taken on the lines 3--3 and 4 4 respectively of Fig. 2. Fig. 5 is a horizontal section of the hanger on the line 5-5 of Fig. 2, the dotted lines indicating how the rollers might be mounted. Fig. 6 is a detail elevation of the outside plate of the hanger, viewed from its inside; and Fig. 7 is a similar detail of the inside plate of the hanger viewed also from its inside.

My invention is shown as applied to a rolling door on the side of a freight car, although it is obvious that it is not limited to this application.

In the drawings the letter F designates the floor of a car overlying a side beam or sill S, and W is the wall of the car alongside of which moves the door D as usual. Beneath the door opening and to one side of the same a track T is mounted on brackets consisting of castings C disposed about eighteen inches apart and held to the sill S by bolts B passing through the track and castings and by lag screws L passing through the castings only; and this construction 1s Specification of Letters Patent.

duplicated in inverted form along the top of the door opening and to one side of the door. For a six-foot opening the tracks will be twelve feet long and the castings C along the top track need not be so close together, or :in fact some other form of guide might be used at the top of the door without departing from the spirit of my invention. I will therefore refer hereinafter to the lower edge of the door only. On the lower track T travels a horizontal roller II having a flange f which moves inside thc rail, and inside the casting at each corner of the door is mounted a vertical roller V whose face travels against the wall lV opposite the sill S. Both rollers are extended as at E at their ends into what might be called hubs to reduce friction. I speak of the rollers as horizontal and `vertical on account of the position of their axes.

Coming now to the details of the present invention, the carri age in which these rollers are supported is duplicated at the lower corners of the door, and as above suggested there may be two other carriages at the upper corners of the door if there is an overhead track of similar construction, and I will describe but one carriage. One member of this carriage I will call the outer plate 1, its body being pierced with a plurality of bolt holes 2 and its lower edge provided with an inwardly projecting lip 3 for a purpose yet to appear. Some distance above said lip the body is provided on its inner face with a horizontal flange 4: having two upright holes 5 and 5. The lip and the flange are at one edge of this member and at its lower end, andy at the other edgethe plate is thickened as at 8 and provided with a socket 9 in its inner face at the center of the thickened portion. Between the lip and the flange the plate is provided with a rectangular opening 7. The other member constitutes what might be called the inner plate 11 whose upper portion is provided with bolt holes 12 registered with those numbered 2 in the outer plate 1, whose lower portion is provided on its outer face with a horizontal lip 13 adapted to overlie the flange 4 and pierced with holes 15 and 15 registering with the holes 5 and 5', whose lower edge is provided with a flange 14 adapted at its inner edge to overlie the lip 3 on the outer plate 1 and formed with sockets 16 and 16 in its upper face directly beneath the holes 5 and 5', and Whose body between the lip 13 and the flange 14 is provided with a rectangular opening 17 for a purpose yet to appear. The parts thus described vare located at one edge of this member, and at the other edge of its lo-wer end its body is thick- .ened as at 18 and provided with a socket 19 in its outer face at the center of the thickened portion.

The bearing for the horizontal roller H is a half-inch steel pin 10 whose extremities are shaped to lit the sockets 9 and 19, and the bearing for the vertical roller V is a quarter-inch steel pin 20 whose lower extremity fits into a socket 16 and whose upper portion passes through the alined holes 5 and 15. It is obvious that this pin need not be so large as that which passes through the horizontal roller H because the latter supports the weight of the door. Ordinary bolts 21 pass through the alined openings 2 and 12 and through the intervening door D, andY hold the two members thereon, the nuts of these bolts being by preference on the outside of the door. In the drawings the position of parts is that which they will assume when applied to the lower right hand corner of the door, plates 1 and 11 will obviously be reversed and the pin 2O mounted in the holes 5 and 15 so that the vertical rollers shall yet project from the inside of the door and travel against the wall W.

' In assembling the parts the pin 10 is put through the horizontal roller H and this roller and the other are placed in position between thetwo members, which latter are brought together so that the ange of one engages the lip of the other as shown. This action will enter the extremities of the pin 10 in 'the sockets `9 and 19. The pin 20 is then dropped down through a hole in the lip 13, through the corresponding hole in the flange 4, through the bore of the vertical roller V, and its lower end into one of the sockets 16 or 16'; and the presence of this pin holds the lower edges of the plates in proper position and prevents their spreading so that the extremities of the lpin 10 could drop out of the sockets 9 and 19. It will be observed that said extremities are not exposed on either side of the door, nor is the lower extremity of the upright pin 20 exosed. The entire carriage is then passed astride the body of the door D, and the bolts 21 passed through the alined holes 2 and 12 and through the door itself, and their nuts tightened up. rThe tread and flange of the horizontal roller H will now be below the lower :tace of the flange 14: on the-member 11, ready to travel on the upper edge of the rail T, and the inner side of the roller V will project through the opening17 and beyond the line of the thickened portion 8 of the member 11, ready to travel against the wall W of the car.V The other lower corner of the but for the lower left corner thedoor is then supplied with a similar carriage, excepting that its parts sho-uld be reversed as above suggested. The upper corners may then be supplied with similar carriages, or with any suitable guide toengage the upper track, and finally the door isplaced in position. All parts of this device are by preference of malleable casting, and in so far as possible I would make the bolts and the lag screws of standard size so that they may be bought in the open market.

A striking feature of the invention is the absence of projections beyond the plates or members, and the simplicity of the struc- Y ture without the sacriiice of advantages. So long as the fasteningbolts 21 hold the carriage on the door, the latter prevents the rise of the pin 20 and the loss of the roller V, and the bolts 21 prevent Vthe spreading of the members and the dislodgment of the pin 10 and loss of the roller H. The vertiv cal roller holds the device away from the car-side, and the flanged horizontal roller sustains the weight of the door and prevents derailmentvfrom the track T if anyfsuitable overhead hanger is employed.
